summary.c calculates the data. It uses some data from cfile, and
adds the per-frame data in tally_frame_data().

Not all the information you need is available. If you want % network
utilization, you need to know the maximum theoretical bandwith of your
network. For most link types, you'll have to ask the user the size of
their pipe... 10/100/1000 Mbps ethernet, 4/16/100 Mbps token-ring, etc.
